New information from Wikileaks revealed the man behind the September 11, 2001, terrorist attacks set his sights on Chicago.
A 2006 Defense Department memo leaked by Wikileaks unveiled that the terrorist made contact with Chicago gang member Jose Padilla in 2002 to discuss future plans, the Sun-Times reports.
The memo revealed the following orders: "Travel to Chicago, Illinois, rent an apartment, and initiate a natural gas explosion to cause the building to collapse."
Padilla also was directed to investigate whether it was possible to set a gas station or hotel on fire in the U.S.
U.S. authorities took Padilla into custody at O'Hare Airport in May 2002 on suspicion of wanting to blow up a dirty bomb.
Padilla is serving a 17-year prison sentence on lesser charges. The White House condemned the release of the classified document by Wikileaks.
